Cathleen Crosby spotted this pair of California Walking Sticks, Timema.

She commented, "Making little sticks." It does look like they might be mating. But I've learned that the smaller male spends much of his life hitching a ride on top the larger female. Doesn't seem quite fair, does it?

Here is a photo Cathleen took several years ago of a single CA Walking Stick.

These insects are only found in the far western United States. They feed on leaves or bark. In our area they might be found feeding on Ceanothus.

Thanks to Cathleen for allowing me to share her photos with you here.
